flywheel

[Oily Fingers]

Just a quick question i got 2 spare flywheels in the garage, and i'm goin to get my crank balanced along with the flywheel and lightening the flywheel as well.  Are the flywheels the same across the mk3 engine?? like is the gt fly the same as the g40???

Hi well i have 3 sitting in the workshop one from a coupe S one from a GT and one from a G40 and to the best of my knowledge they are all the same, they defo look all the same (G40 one is now litened and balanced but it did look the same,lol)
You will also need the relevant clutch cover bolted to the flywheel when they come to balance the full assembly for the best results.

kool cheers!!

yeah i'm now on the hunt for the clutch, but cant make my mind up between helix paddle one of organic one!!!  once i get the clutch i'll be dropping the assembley off for the work.

[leeg40]

I opted for the helix ceramatalic paddle, looks good quality, but i have not run it yet so cant comment on how it drives.

[hayesey]

Personally I wouldn't recommend a paddle in a car that's going to be used daily.

yeah, was kinda leaning towards the organic helix one as my mate had a paddle fitted to his rs turbo and that was sharp as fook.

where would be the berst (ideally the cheapest) place to get an organic set up?

did anyone decide how much to take of in the end? I read a few threads regarding this, or is it a case of who machines it and their experiences with such things..

Thats is one thing to bare in mind, but mine is not a daily hence the choice of clutch.

Dont any of the traders on here sell clutch kits?

If not you could try, Bill at badger 5, backdraft motorsport, JBS now stock helix iirc, jabbasport still stock sache i think, G-werks may beable to help? or one or to crop up on ebay now and again.

That was the case for me, take it to any good builder and they will know exactly what the limits are.

Fair one mate.. I know a few machine shops who could do it for me, so we'll see. The thing is, part of me wants to wait until i build a new engine   (one day) and get it all done proper and dynamic balance all rotation masses ie crank etc... so i was wondering if this is worthwhile.. the engine is an afh running on a basic carb set up.

yeah, the place i go, the dude  that does the machine work for me, build engines for several raceing teams in diffferent types of motorsport. and the workshop there is my idea of heaven!!!

Julian Godfrey's in Heathfield used to do all the flywheels for PSD. Irrc they took off approximately 1.2kg which is around the 20% mark...

I know that a lightened fly wheel let's the engine rev more freely and by lightening it you loose the stabilty slightly so it's more sensative but what do you realy gain from doing it just better response ?? Jst wondering as I've got to get mine skimmed and not sure weather to bother having it lightened aswell doesn't it weaken it aswell ??

[jez1272gt]

yeah by reducing the mass of the flywheel this will encourage a slightly free-er rotating engine, meaning increased acceleration. Removing material from the flywheel will reduce the strength however as long as the correct amount is removed from the correct area then this should be of no concern to safety!
